ro ALL WHCM I'r MAY C CNCERN: i y -Be it known that we, EDMOND RICHARDSON and JAMES H. COLE, both of the city of Adrian, in the county ot`Lenawee, and State of Michigan, have invented a new and useful Improvement in Method of Forming Roofing, and machine for making the same; and wev do hereby declare that the followingrs a'clear and exact descripv tion, which will enable others skilled in the art to make and use the same, reference being had to the accompanying d rcwi-ngsand to the letters of reference marked thereon. In the drawings- Figure 1 represents a perspective view of the rollers A and Band the frame F und handle H. Figure 2 represents :Lperspective view of the same, and, in addition, the frame D E of the bed. and also` thesteel strips z' and '1. I i

Figure Srepresents an end view of thembed D E and steel strips z'and 1. Figure 4 represents an end view of the same with the roller C placed in working position upon them.

i The nature of our invention consists in the mode or process of manufacturing Jay J. Wiggins Egyptian case-hardened marble, (patented December 4, 1866,)- and also all other plastic material, into sheets for rooting by the rolling process. i t

To enable others skilled in the art to make and use our invention, we will proceed to describeour process,

and the construction and operation of the devices which we employ therein. I i First, we construct a. sand-bed to form Vthe groundwork on which to-forin the sheets, -and this is accomplished in the following mannen'lake two long, square sticks of timber, of suitable size, and bed them into the ground, parallel to en.ch other, and a distance apart, from centre to centre, equal to the width required Ytiel?! the sheets, and between their endst in end pieces, thus forminga parallelogram. Through the middle of the,

uppcr'sidc of 4the longer pieces, we insert steel strips of convenient width, andas far between them as the sheets nre wide,` as long as the timbers, and their lower edges embedded into the timbers far enough to 4support them up'edgewise, the upper corner bevelled ofi' on the outside to a sharp edge projecting above the timbers half an inch or more.

Next, we fill up the interior with sand, wet'and packed down, :md strike `it o with astraightsedge. We now run-the roller C over it, as represented in gi, the body of the roller extending as far belowithe top of the steel strips as is required for the thickness of the sheets. i

The bed being now prepared, we next prepare the smellA roller 13 which can be readily detached from the frame F by an adjustable pivot. This done, the roller is next wound with a sheet of felting or peper,- which should be somewhat wider than tho bed, and then placed back in the frame. The felting is then drawn over the roller A in the direction indicated by the arrows in iig. 2, und drawn around under the large roller, and al1 then Vplaced at one end of the bed.

We now commence pouring tho plastic material upon the bed, and at the `suine time m ove the roller A forward lengthwise of the bed, the folting forming the upper surface of the sheet', and occupying the position represented by the purple lines of-iig. 2, the felting or paper being paid out by the roller B as fast as required by roller A. The roller A and the edges of the steel strips z' and 1 cut the feltingthe required width.

The scrapers o in frame F take oit' the surplus material that may chance to adhere to the roller A, when not protected by the felting.

, The top of the hed may be sprinkled with ground slate or marble, or any other material desired for o surface for roofs.

Sheets made of materiel not heated lcan be taken up immediately; if heated,v tbeyeanbe taken up as soon ns cool.

Hoving thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1.- The method herein described of making sheets or Egyptian case-hardened marble, or sheetsof any similar material, by the application of the felting simultaneously with 'the rolling and pressing of the sheetsy substantially as described.

2. The'vonstructionof ytlie rolling-instrument showin in fig. `1, Having the rollers A'nnrl B, the former'beng Y provided with shoulders, m and n; and sferapers,y o o, substantially as -and for the purposes set forth.

3. In combination kwith said instrument, we 4claim the frame I) E, when vprovided with the cutter-etz' 2', substantially as describedvand for thek purpose set forth. A Y
